Aperture does not see all of my Photos

Hello all - today I noticed an interesting issue. After running the latest release of updates today (ilife, raw camera, etc.) Aperture 2.2.1 (whatever the latest release) no longer sees all of my photos - about half of my projects are missing from the Aperture program itself, however they are still in the library as I can get to them in finder.

Anyone have any ideas on how to fix this? I have tried redirecting to my library and that did not work.
